RedSim eSIM Data Plans for Singapore

RedSim does not provide a genuinely unlimited data eSIM for Singapore. Its plans that carry the “Unlimited” name actually offer a capped high‑speed allowance of 3 GB per day; once that daily limit is reached the speed drops to 1 Mbps for the remainder of the day.

Travelers who need larger data volumes can choose from RedSim’s fixed‑data plans that last 30 days, such as the 20 GB plan priced at $17.33 USD or the 50 GB plan priced at $30.00 USD, both of which provide full‑speed data up to the stated limit and expire after the 30‑day validity period.

RedSim does not provide an eSIM for Singapore that includes a phone number or SMS capability. The available plans from this provider are data‑only, offering mobile data without inherent voice or text messaging services.

Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage through the data connection, but some destinations may restrict or block specific apps or services. It is advisable to confirm that the messaging platforms you rely on are accessible in Singapore before purchasing a plan.

RedSim offers 22 single‑country plans that cover only Singapore and 17 multi‑country plans that also include Singapore. The single‑country options range roughly from $1.79 to $30 and provide between 1 GB and 15 GB of data, while the multi‑country choices are priced between about $4.50 and $63.80 and can include up to 50 GB. Some plans are fixed data caps that give a set amount of data for the whole validity period, whereas others are daily data cap plans that reset the data allowance every day, giving customers a flexible range of usage patterns.
